how to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.
I have a date/time stored in a smalldatetime field (ms sql 2005) that i want to compare with the current time and receive a difference. If the difference is less than 30 minutes, do this....if more do that....
My problem is that I have a grid view that show the data from database.In my gridview i add a column name date .like eg You knw that when we send a scrap to anyone then show time how much time to send a scrap.
This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then Try If pasDate <= System.DateTime.MinValue Then Return Nothing Else Return CType(pasDate, DateTime) End If Catch ex As NullReferenceException Return Nothing End Try Else Return Nothing End If End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.
I have a gridview on my page. I have a checkbox in each row of this gridview. For each checkbox in the gridview, I'd like to update my table accordingly, but I don't want them to have to hit a submit button every time they check the checkbox. I want them to check all the boxes they need to and at the end, they should hit one submit button.
I have 2 fields being displayed in a Gridview, StartTime, EndTime. I want to create a 'Time" column which shows the elapsed time in HH:MM format. (StartTime - EndTime) This was all generated with VS2008, table is pulled from an SQL Query.
I'd like to generate an OId number in a specific textbox on a specific page which comes out of date and time, for example if today is may 27th 2010, 9:45 am,it will generate the number 270520100930
I am trying to develop a piece of code that will allow a user to enter data into a text box and have the option creating another textbox to enter more data. Here is my code. The issue I am running into is the dynamically generated textboxes overwrite the previous one.
I am creating a system in ASP.NET VB whereby a user can enter data into a textbox and the data is populated into a label - easy right? Well, yes the first time is easy. But what I need is... kinda like Twitter, one textbox, multiple labels. Each entry into the textbox will populate a new label (an empty the textbox) without loosing the labels that currently hold data that has previously been entered.
generating random numbers in texbox and then submit to database. code should check if the generated number already exist in database before submiting to database.

I coded in code behind to dynamically generate a gridview as the columns of the gridview changes based on user selection. In the gridview I have dynamically generated controls like textbox, dropdown list etc.I have a few filtering options about, for example: listbox which will postback on change and causes the gridview content to change as well.My problem is: since the controls are randomly generated and every postback will read dataset from database and reload, the naming of the controls are dynamically generated too.
